Robert Pattinson may seem super laid back, but when it comes to making Kristen Stewarthappy, he goes the extra mile — especially in celebrating her 22nd birthday last Saturday! As we already reported, the couple spent the evening at one of their favorite bars, Harvard & Stone, in Los Angeles April 7, but we have all new details that will make you swoon.

“This wasn’t an impulsive visit at all,” an insider tells HollywoodLife.com about the intimate bash. “Rob planned the whole thing a few weeks ago. He talked to the owners and managers about it and wanted to make sure everyone could get in and out without too much trouble.”

In fact, Rob, 25, wanted to make sure everything went off without a hitch — but he didn’t want the party to be too over the top.

“They wanted some privacy, which is why they were in a reserved spot, but there wasn’t a birthday cake,” our source says, explaining, “At one point, it was offered but Rob declined. He just wanted a fun night out with friends.”

Even though the party was low key, Rob had some fun tricks up his sleeve, even inviting some guests who surprised Kristen.

“It wasn’t a surprise party, per se, but Kristen did seem surprised by some of the friends who showed up,” the eyewitness remembers. “Rob and Kristen seemed so comfortable with each other, holding hands and putting their hands on each other’s backs occasionally. They were making goofy faces for pictures and everyone was just having a great time.”

We bet Kristen couldn’t have asked for a more fitting way to spend her 22nd birthday. Doesn’t Rob sound like the sweetest boyfriend?
